don't include dotfiles in gem

[danbernier]

Fixes #227.

Here's the proof that it works:

I don't mind not packaging dotfiles with the gem in the future but imo this is something your project should fix. If you are vendoring your dependencies into your repository for whatever reason, have rubocop skip them.

Thanks!

Agreed, but like I said in a comment on the issue:

I tried that, but it still finds the .rubocop.yml in there. My hypothesis is that the logic for finding config files is different from the logic for finding files to lint.

Yeah, though, it's kind of a hash of an issue. Thank you for accepting the PR despite that!
